Hide 'Wait' if WebViewActivity error is not due to external bus timeout (#4412)

* Hide wait if WebViewActivity error is not due to external bus timeout

 - The error pop up in WebViewActivity can show up for various reasons. The option to wait is only relevant when it is due to a timeout waiting on the external bus, otherwise it is an error for page loading/ssl/...  where waiting won't change the outcome. To prevent confusion, hide the wait button when the error is not triggered by the external bus timeout.

* Align refresh button text and action

 - Have the refresh button trigger refresh errors instead of timeouts by using the correct url + function instead of interacting with WebView directly (for previous commit to work as expected)
 - Make the text on the refresh button and the action do the same thing by using the same check for internal
